Why Do Women Live Longer Than Men

Everywhere in the world women live longer than men - but this was not always the case. The available data from rich countries shows that women didn't live longer than men in the 19th century. Why do women live so longer than men, and why have these advantages gotten bigger in the past? The evidence is sketchy and we're only able to provide limited solutions. Although we know that there are biological, psychological as well as environmental factors which play a significant role in women who live longer than males, we aren't sure how much each one contributes.

In spite of how much number of pounds, we know that at a minimum, the reason why women live longer than men, but not previously, is to have to do with the fact that a number of key non-biological factors have changed. What are these changing factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Certain are more complicated. For example, there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women's longevity disproportionately.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and افضل شامبو وبلسم women. As we can see, all countries are above the diagonal line of parity - which means that in every country the newborn girl is likely to live for longer than a new boy.1

It is interesting to note that although the female advantage exists everywhere, the difference between countries is huge. In Russia, women live 10 years longer than men. In Bhutan there is a difference of just half a year.

The female advantage in life expectancy was less in the richer countries than it is today.
Let's now look at how the female advantage in longevity has changed with time. The chart below illustrates the gender-based and female-specific life expectancy at the birth in the US from 1790 to 2014. Two specific points stand out.

The first is that there is an upward trend. Both men and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is widening: While the advantage of women in life expectancy used to be extremely small It has significantly increased over time.
